Hi trippy,.. seek help where you can find it and if it doesn't sit right with you seek it some more..

I read your original post, I am sorry about your mother and your family situation, that in itself is hard enough to move on from..
.. if at all possible, try not to think about the religious component.. I was raised fanatical Pentecostal born again Christian.. You do not have a demon soul etc.. It is just a term 'religious' people use because they cannot "remedy" this person with immediate prayer... That is not me trying to undermine your upbringing or beliefs, I always tell ppl not to confuse God with religion..

Seek help.. 16 is a tough year.. I wish I had of sought help then...
